The term "Trigger Points" was introduced by Janet Travell (1901-1997) in 1952, although the concept had been known in "official" medical circles for at least a century, although in a more vague manner.

But we believe we can say that the concept was well known in traditional medicine, though of course not in the scientific details accurately described and systematized by Janet Travell, an exceptional scholar who among other things was also the personal physician of J. F. Kennedy, and the official physician of the White House during the Kennedy and Johnson administrations.
